Using the most comprehensive fish occurrence database, we evaluated the importance of
ecological and historical drivers in diversity patterns of subdrainage basins across the …

In the last decades, knowledge about the biology of the Amazon river dolphin Inia
geoffrensis has increased considerably. Accordingly, we present a review of the published …

Cryptic biodiversity continues to be revealed worldwide, even in apparently well-known
groups such as carnivorans. The Neotropical Otter (Lontra longicaudis) presents shape …

Abstract Night monkeys (Aotus, Cebidae) are a widely distributed genus of Neotropical
primates with a poorly understood taxonomy and biogeography. The number of species in …

We analyzed 156 specimens of diverse howler monkey taxa (Alouatta; Atelidae, Primates)
for different mitochondrial genes (5,567 base pairs), with special emphasis on A. palliata …

A first step in protecting groups of similarly structured organisms is to place them into
discrete taxa. Molecular genetics and phylogeny allow us to rebuild the evolutionary history …

The species within Xenarthra (sloths, anteaters, and armadillos) are quintessential South
American mammals. Of the three groups, Vermilingua (anteaters) contains the fewest extant …

Abstract Knowledge of how a species is divided into different genetic units, and the structure
among these units, is fundamental to the protection of biodiversity. Procyonidae was one of …

We sequenced mitochondrial genes ND5, 12s rRNA, and COI in 302 Andean or spectacled
bears (Ursidae) from Venezuela, Colombia, Ecuador, Peru, and Bolivia. Of this total, 294 of …

Importance of the work: Irrawaddy dolphins have experienced demographic decline. The
lack of genetic information might hamper management decisions necessary for restoring …
